Some specific types of tubular rivets areĬompression Tubular Rivets: A compression tubular rivet (fig.
They are normally used for commercial applications rather than in the aerospace industry. Since extensive cold forming is required on these rivets, they must be extremely ductile and are consequently made of low strength materials. The hollow end is cold formed to a field head. The generic form has a manufactured head on one side and a hollow end that sticks through the pieces being joined. Tubular Rivets: Tubular rivets are partially hollow and come in a variety of configurations. They are used primarily for commercial sheet metal applications. Although drive-pin rivets can be installed quickly, they are usually not used in aerospace applications. The head is normally hexagonal to prevent rotation of the tubular body while the mandrel is being torqued and broken off.ĭrive-Pin Rivets: This rivet has a drive pin that spreads the far side of the rivet to form a head, as shown in figure 38. 37(a)) has a threaded internal mandrel (stem) with the external portion machined flat on two sides for the tool to grip and rotate. Threaded-Stem Rivets: The threaded-stem rivet (fig. A generic pull-mandrel rivet is shown in figure 36. When the proper load is reached, the mandrel breaks at the notch. Pull-Mandrel Rivets: This rivet is installed with a tool that applies force to the rivet head while pulling a prenotched serrated mandrel through to expand the far side of the tubular rivet.
SPLIT RIVET INSTALL
SPLIT RIVET PORTABLE
The installation tool is portable (comparable to an electric drill in size).Only one operator is required for installation.They have the following significant advantages over solid rivets: 35), to increase the shear and fatigue strength while still maintaining a flush fit.īlind Rivets: Blind rivets get their name from the fact that they can be completely installed from one side. The sharp edge of the countersunk head is also removed in some cases, as in the Briles BRFZ “fast” rivet (fig.
Note also that the countersunk head angle can vary from 60° to 120° although 82° and 100° are the common angles. However, because the “experts” do not necessarily agree on the names, other names have been added to the figure. Although most of the solid rivets listed in table IX have universal heads, there are other common head types, as shown in figure 34. Note that the rivets in table IX are covered by military standard specifications, which are readily available. Some other solid rivet materials are brass, SAE 1006 to SAE 1035, 11 steels, A286 stainless steel, and titanium. A representative listing of solid rivets is given in table IX (ref. Thus, solid rivets must have cold-forming capability without cracking.
Solid Rivets: Most solid rivets are made of aluminum so that the shop head can be cold formed by bucking it with a pneumatic hammer. From a structural design aspect the most important rivets are the solid and blind rivets. The general types of rivets are solid, blind, tubular, and metal piercing (including split rivets).
